Bandgap determination of P(VDF-TrFE) copolymer film by electron energy loss spectroscopy
Source abstract
Abstract
The ferroelectric β of poly(vinylidene fluoride trifluoroethylene), P(VDF-TrFE) is confirmed for 100 nm thickness spin coated copolymer film. The homogeneous coverage of the copolymer film is investigated by the help of X-ray photoelectron spectroscopy (XPS). Most importantly, the existing bandgap in the crystalline phase of the copolymer is determined directly from the electron energy loss spectroscopy (EELS).
